To all whom it may concern.'

.. Be itlqmoWnthatI,V WILLIAM F. KIESEL,

and resident of Altoona, county of Blair, State of Pennsylvania, have invented certain new and useful Improvements in Cfrirakes, of

which the followingr is a specification.

My invention relates to car brakes generally and more particularly to a clasp brake arrangement for siXjeWheel-trucks.

It is the vprincipal object cf my invention to Varrange a brake on the tfk so that it will practically consistv of four units, tw each side of the transverse center line thiir-li ,the 'center plateof the truck. Each unit includes tliiee heads. The advantage of this arrangement' vides better means for equalizing aid less angularity for brake levers. Excessive distortin of the brake levers is 'objectionable when shoe wear takes place. Afurther object is te locate the live and dead primary levers" asiear te thetrans verse center line through the truck pivot as' is possible and to apply the general scheme shown in my Patent No. 1,092,917 of April- 14, 1914., t0 six-Wheel truck construction.

The above vand other the axles are mounted the side frames which comprise two similar channel bars 16 and '17 having the channels thereof disposed oppe= site to ea'ch other and the beams .are bolte together to form a rigid construction 'and at their ends the side frame members made up of the two beams end frame members. 18' and 19. Suitable pedestals are provided for supporting the side frame members on the axles.

The 'brake devices on ueach side ofjthe truck are alike and I lvvill therefore describe the braking devices on one side of the truck only, it being understood that the same description applies to the opposite side.

is-'that it prov` objects and the `novel l feature of my' invention will be-appaiet` f 'side of the bolster' are secured together by the Brake 2 0 and 21 carry brake shoes which engage the tread of the wheel 13 on opposite sides of the axle 10. The brake head 20 is suspended fronithe end transverse frame member ,18 by means of a link 22 and the brake head'20 is also fastened to theJend of a brake beam 23 whereby the brake beam 23,'.which extends across the end of the truck, hangs from' the hanger rods 22 .depending fromtlie frame on opposite sides of the truck. Safety hangers are provided 1n the form of links`24lhung from the transverse frame member `18`=and attached to the brak'e beam by a lug 25. These links are placed on opposite sides ofthe longitudinal center line of the trl and "are longer than necessary to hold up the brake beam and do not become effective until some supporting pai-'tfor the brake beam breaks, in which case links prevent the beams from falling to the track.

The brake head 21 is hung by means of'a link 27' from a bracket 26 riveted tothe side frame member 16 and a similar link 28 on the opposite side of 4the bolster 29 suspends the brake head 30 from the bracket 31. The

. shoe carried by' thebrake head 30 engages the tread of the center wheel 14 and on the opposite side-of the axle 11 of the Wheel 14 there is a similar brake head 32, the slice on which engages the tread of the wheel lifl The brake Yhead 32 'is hung;v by means of thelink 33 from a-braclret 34 riveted to the side frame member 16. On the opposite 31 there is a. Similar link 35 which suspends the brake bracket 37 riveted to the side frame member 1G..

The shoe on the brake head 36 iS capable of engagincuthe; tread the opposite side of similar brake head 38, the shoe of which also engages the tread of the wheel.. 15. The

brake head 3S is similar in allfrespectsto the and adjacent line of the truth the truck 19 by means of theV` On opposite sidesefthelengihead 36 from a ofthe wheel 15 and on' the agile 12 there is a primary brake levers 41and42. The upper end of each of the brake levers 41 and 42 is flexibly connected by a link 43 and brake rod 44 to an equalizing lever not shown, which is located 'near the brake operating devices at'some convenient place on the car.' The link 43 and Irod 44 are flexibly connected togetherby a swivel connection 45.l

The connections of the levers 41 and 42 to the brake heads are in all respects similar and only the connection of the lever'41 will' be described. Thelower end of the lever 41 is pivotally connected by the link 46 to a point intermediate the ends of a secondary brake lever 47 which is horizontally disposed, while the lever 41 is disposed in a v vertical planeo, The outside end of the secondary brake lever 47 is pivotally connected to the brakeI head 32 while the inside fend of the lever 47 is connected by means of a link 48 to the inner end of a third or l e tertiary brake lever 49. The outside end of the brake lever 49 is pivot-ally connected-to the brake head 36. Intermediate the ends of the brake lever 49 it is pivotally connected to a rod 50 which extends rearwardlyand parallel to a rod 51 on the opposite side of the center line of 'the truck. The .rods 50 and 51 are pivotally connected to the brake beam'40 on-opposite sides of the center line spectively connected to the primary dead@ levers 53 and 54 by means of the equalizingbars' 55 and 56. The primary levers 41, 42 and 53, 54, are located on opposite sides of the'center axle 11 and the equalizinp,` bars 55 and 56 extend across the transverse center line through the truck pivot. The primary levers are located as nearly as possible to -the transverse center line through the truck pivot andare disposed in the same plane.

' `The upper end of each of the primary dead levers 53 and 54 is pivotally anchored byl a rod 58 to a part of the truck or it may be anchored to brackets or other devices of the car body which are located near the transverse center line of the truck pivot in a manner similar to the construction shown lever 61 is pivotally connected to the brake head 30 and the inner end is connected by means of a link 62 to the inner end of al 63. The outer end of the brake lever 63 y is pivotally connected to the brake head 21 and intermediate its ends it is connected to' the end of a rod 64, the other end of the said rod being' pivotally connected toI the brake bearn 23 and beingl disposedsubstantially parallel to the rod '65 on the opposite side of the longitudinal center line of vthe truck. The rod 65 is connected in a similar manner to the brake beam 23 and both rods 64 and 65 have devices 66 whereby the length thereof may `be adjusted. e f The links 48 and 62 and the corresponding linkson the opposite side of the longitudinal center line of the truck pass through box brackets 68 secured to the undery side of the transom whereby the inner ends of' the secondary and tertiary brake levers are suitably supported.

It will be seen from "the foregoing description that the brake on each truck consists of practically four units,'each unit comprising three brake heads connected to a primary brake lever through a secondary and tertiary brake lever. Each primary brake .lever is located substantially on the trans! verse' center line of the truck through the truck pivot, the end brake heads being con nected together and serving in a degree to equalize the braking effort. The main equalization of the braking effort is obtained by a primary equalizing lever located at any suitable point on the car. f

umerous changes may be made in the details of construction Without departing from the spirit of the invention and therefore I do not Wish to be limited to the exact devices shovvnand described.

Having described my invention what I claim and desire to secure by Letters Patent vIs,
